Every day, at 18:00hrs, my Windows XP-based desktop PC performs a full backup of its hard disks to a NAS appliance. The backup takes advantage of Windows' "Volume Shadow Copy Technology" to ensure that no files are skipped during the process.
XP's backup software generally performs its task well and I've been extremely grateful for it on those few occasions when I've had to restore a "broken" system. It's never failed me, until today...
At 18:00hrs today my backup process, running via XP's scheduler, started up as normal. Then terminated immediately. Now I'll admit, I recently purged some accumulated detritus from my hard disks, but I didn't think I'd deleted enough to render backups instantaneous.

Thank you Microsoft for another clear, concise and meaningful error message!
So I copy-and-pasted "

There were a couple of documented "solutions" but, unfortunately, none of them worked for me. There were also a lot of long forum threads that described the problem but closed with it unresolved. Not a good sign!
Thankfully, I did manage to get the backup program working again. Here's how I did it:

HKEY_LOCAL_MACHINE/system/setup"; Change the "
UpgradeInProgess" value to "
0" ; Change the "
SystemSetupInProgress" value to "
COM+ Event System", "
COM+ System Application" and "
Volume Shadow Copy" services.
Windows XP Backup worked perfectly once these operations had been performed.
 The "
UpgradeInProgress" key might not exist in the Registry. If it doesn't there is no need to create
